ingredients & substitutions

Below you will find a few notes about some of the ingredients. For a full list of ingredients and quantities needed for this recipe, see the recipe card at the bottom of the page.
- Bananas – the more ripe the bananas are, the sweeter your muffins will taste. Grocery stores often have carts of fruit on sale and you can sometimes find overripe bananas there! Look for bananas with brown streaks that are nicely ripened.
- Egg – Bring egg to room temperature by taking it out of the refrigerator 30 to 60 minutes before baking these muffins.
- Melted butter – Melt the butter for the muffin batter, then let it cool for a few minutes before adding it to the eggs for that step in the recipe.
- Blueberries – you can use fresh blueberries or frozen. Sometimes frozen blueberries can have a tendency to ‘bleed’ all over the batter, even when they are added straight from the freezer. To avoid this, toss the blueberries in 1 tbsp. of flour to coat them before adding to the batter.
- Rolled Oats – I know, the photo says oatmeal. For some unknown, reason I’ve done this so many times in my recipe. It’s rolled oats!! I like to use quick cooking oats in these muffins. You can also use old-fashioned rolled oats which will give you a chewier texture and thicker muffin.
- Brown Sugar – light brown sugar or dark brown sugar will work as well.
- All-purpose flour – you can substitute half of the all-purpose flour with whole wheat flour.
step-by-step instructions for blueberry banana muffins
Preheat oven to 375°F. Grease 12 muffin pan and set aside. Alternatively, you can use cooking spray or line the muffin pan with paper muffin cups.

In a large mixing bowl, whisk together dry ingredients.
In a separate bowl, melt butter in microwave in ten second increments just until melted.

Next, in a medium bowl, combine mashed banana, sugar, beaten egg and melted butter. The melted butter must be cooled before adding it to the mixture.

Add banana mixture to dry ingredients and stir just until moistened.

Gently fold in the blueberries and stir just until combined.

Divide batter evenly in twelve regular-sized muffin pan.
Make the streusel topping: In a small bowl, combine brown sugar, all-purpose flour, cinnamon and butter.
Sprinkle evenly over top of the muffins. You can also sprinkle with a few rolled oats on top of each muffin which gives it a pretty finish.

Bake in 375°F oven for 17 to 20 minutes. Cool for a few minutes, then transfer to a wire rack to cool. We loved the blueberry flavor combined with banana.
I hope you enjoy these banana blueberry oatmeal muffins recipe as much as we do!

Absolutely love this recipe! It’s definitely graduated into the regular rotation! Awesome way to use up bananas and blueberries at the end of the week so they don’t go bad
I followed this recipe as written except I used whole wheat flour. They were so delicious. I will make them again and add walnuts.
These muffins are delicious. I used whole pastry flour because it’s lighter than AP whole wheat. I didn’t make the streusel topping. I added the cinnamon, nutmeg, ground ginger and cardamom. So darn good. My family and neighbors loved them.
